NFL Players Association President J.C. Tretter is pushing for daily COVID-19 testing during the regular season.

The NFL has been conducting daily testing for players throughout training camp and plans to do so through Saturday.

“In the spirit of adaptability, expect the NFLPA to push for modifications or updated recommendations — such as the continuation of daily testing — as the season progresses and new information becomes available,” Tretter, the starting center for the Cleveland Browns, posted on the union website. “We will continue to rely on scientific data to inform our approach for combating this virus. As the science evolves, we will evolve with it.”

Tretter added he was pleased with the protocols the NFL and NFLPA agreed on for training camps. The league has reported few positive cases in the past month, though it did have 77 false positives a week ago that resulted from contamination at the testing lab.

Iowa State will allow about 25,000 football fans into Jack Trice Stadium for the Cyclones’ opener against Louisiana-Lafayette on Sept. 12.

Athletic director Jamie Pollard wrote in a letter to fans on Monday that the crowd will be made up of season ticket holders only. Fans will be required to wear face coverings at all times and no tailgating will be allowed. Pollard asks that fans respect others’ wishes for physical distancing.

“An important factor in the decision to allow fans is our belief that Cyclone fans are willing to adhere to our mitigation measures,” Pollard wrote. “The purpose of this letter is to ask for your support in helping create a safe environment while also providing our team an impactful home field advantage. This is an incredible opportunity for Iowa State University to showcase its ability to successfully navigate the challenges associated with large outdoor events during a pandemic.”

Pollard said if mitigation actions are successful, Iowa State will allow season ticket holders to attend the game against Oklahoma on Oct. 3. He said if it’s determined mitigation measures were not followed adequately at the first game, no fans will be allowed the rest of the season.
